Abstract (en)

[origin: WO9846541A1] A new method (P200) is provided for making magnesium oxide layers (122) in plasma displays (100). A magnesium carboxylate liquid precursor solution is applied to a display panel (102), dried, and annealed to yield a solid magnesium oxide layer (122) having excellent electro-optical performance.
